Heard reportedly asked to Scott to discuss the expenses with her Monday, a discussion which would have included a Chicago Public School Inspector General investigation.
But that next morning at 3:20 a.m., police found Scott's body in Chicago River by the Merchandise Mart.

"They're trying to say that Michael Scott committed suicide over that. I mean, you people are just - I guess you want to dig him out of the grave or something," said the mayor. "It had nothing to do with it. If you could predict why someone committed suicide, you'd be the greatest psychiatrist in the world. It had nothing to do with Michael's death, suicide."
